Is this a right way to use "to no avail"? [closed]

But to not his avail,they didn't pay him any attention.

Solution 1:

That is not the right way to use to no avail.

To no avail is an adjunct of result in clause structure with a meaning similar to unsuccessfully, with no result, or fruitlessly. It is pretty much a set phrase that does not permit the addition of other elements. The no may be swapped out for little, much or what depending on the degree of success or interrogative use.

Besides this, your sentence is defective in that the main clause is concerned with what they did. What you need is a main clause about what he did to no avail.

e.g.

He atttempted to enter the conversation several times to no avail.
